soc/amd/picasso: fix MCACHE on psp_verstage RO boot
On RW boot path psp_verstage call cbfs_map which calls chain of
_cbfs_alloc, cbfs_boot_lookup and cbfs_get_boot_device. Then
cbfs_get_boot_device initializes MCACHE which is used later.
However on RO boot path psp_verstage doesn't try to find anything in the
CBFS which results RO MCACHE not to be initialized. Add
cbfs_get_boot_device(true) to explicitly initialize MCACHE on recovery
boot.
